Quoted from KSUWildcatFan:it looks like I'm going to be pulling the bank around that left switch and hoping I can get it back in.
So I'm thinking you'd like to jump the #7 Pin Relay to another Pin Relay to see if it pulls
when the one that it's jumped to does. There should be a switch in the Pin Relay's stacks that
go to the Hot lug of their coil. That should be easy to get an elegator clip on. Now if you
can get another clip on the common neutral lug which may have jumpers to other coils.
btw: Can you see a number on one of the Pin Coils? Also, being a 1949/1950 machine, are
they 30 volt coils?
